If you use a 1500 or smaller truck then yes, you need both. I only use a weight distributing hitch with my 2500 Ram and tow up to 12K lbs with up to a 32' trailer with 5200 lb axles. Like said above, more info is needed, like how much weight you are pulling, what size trailer, and of course what tonnage of truck.


The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
